Summary: Atomically thin superconductivity in Pb monolayers grown on Si(111) is affected by the addition of a small amount of Au atoms, which decorate the atomic step edges of Pb/Si(111) and link the electronic reservoirs of neighboring atomic terraces. This enhances the propagation of superconducting correlations across edges, facilitating coherence between terraces and promoting macroscopic superconductivity at higher temperatures.

Summary: Currently, finding a new catalyst for electrocatalytic hydrogen evolution has become crucial due to the high price and scarcity of the precious metal Pt. In this study, the electrocatalytic activity of Janus MoXTe (X = S, Se) monolayers for hydrogen evolution reaction (HER) was investigated. By introducing vacancies, the catalytic performance was improved, especially with Te vacancies in 2H phase MoSTe and MoSeTe, which showed the highest exchange current density and enhanced conductivity. Our research provides a strategy for designing MoXTe monolayer electrocatalysts that are predicted to have low cost and high performance for HER.

Summary: This study developed a series of Na2Ca1-x-yCexMnyP2O7 phosphors using the solid-state reaction method in an H2-N2 environment. The crystal structure, valence state, emission behavior, energy transfer mechanism, and thermal quenching behavior of the phosphors were investigated. Doping with Ce3+ and Mn2+ ions improved the photoluminescence properties of Na2Ca1-x-yCexMnyP2O7, and the addition of Mn2+ ions led to the emission of white light. Energy transfer from Ce3+ to Mn2+ ions was observed, and it was governed by dipole-quadrupole interaction. These phosphors have potential applications in high-power LEDs due to their white light emission, high activation energy, and low thermal quenching behavior.

The CuO thin film was deposited using Chemical Vapor Deposition, and the sensing response was improved by forming heterojunctions with rGO. The developed sensor showed high selectivity towards H2S gas and the improvement in sensing response was attributed to increased hole concentration in CuO and increased absorption of H2S molecules.

Summary: This study investigates the thermodynamic stability, electronic, and thermoelectric properties of TiB2 and ZrB2 using density functional and Boltzmann transport theory. The results show that the ZrB2 monolayer exhibits dynamic instability in phonon band dispersion, which can be improved by biaxial strain. The electronic properties of the monolayers do not change significantly. The strain modulated Seebeck coefficient, electrical conductivity, and electronic thermal conductivity are studied, revealing a decrease in Seebeck coefficient and an increase in electrical conductivity and electronic thermal conductivity with increasing temperature. The lattice thermal conductivity is found to be higher in TiB2 monolayer compared to ZrB2 monolayer. These findings suggest that strain can enhance the dynamic stability and modulate the thermoelectric properties, and TiB2 monolayer may be a potential low temperature efficient thermoelectric material.

Summary: The magnetic ground state of the LaCrO3 and CaCrO3 solid solution, La1-xCaxCrO3 (@ 0 <= x <= 1), is investigated in this study to understand the magnetic phase transitions with Ca substitution. Using density functional theory with Hubbard correction, the system exhibits transitions from antiferromagnetic insulator (x = 0) to ferromagnetic half metal (x = 0.75) to antiferromagnetic metal (x = 1). The introduction of Hubbard energy U and Ca substitution affects the Cr-O hybridization, as observed in the partial density of states. The study presents a compositional phase diagram with the magnetic ground state for the La1-xCaxCrO3 (0 <= x <= 1) system.

Summary: In this study, researchers reported a highly sensitive and selective NO2 sensor fabricated through low-cost and scalable methods using a hybrid nanocomposite of two-dimensional Al70Co10Fe5Ni10Cu5 quasicrystal (QC) nanosheets and MoS2 nanoflakes. The Al70Co10Fe5Ni10Cu5/MoS2 heterostructure showed an excellent gas-sensing response of about 66%, which is 2.27 times higher than that of the pristine MoS2 nanoflakes-based sensor. The integration of the 2D Al70Co10Fe5Ni10Cu5 QC with MoS2 nanoflakes holds great promise in the design and development of NO2-based gas-sensing technology.

Summary: In this manuscript, the room-temperature properties of CuO and Cu0.995La0.005O ceramics synthesized by solid-state reaction method were investigated. La doping in CuO leads to the evolution of compact and dense microstructure with reduced porosity. The La doping induces strain in the CuO lattice resulting in a reduction in the lattice parameters and cell volume. The dielectric constant of Cu0.995La0.005O ceramics is enhanced and the leakage current is reduced, attributed to the dense microstructure and strain in CuO lattice after La doping. The bandgap of Cu0.995La0.005O ceramics decreases due to increased vacancy defect concentration, and the magnetic and dielectric properties are correlated with the grain size in La-doped CuO.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
